Can I use 87 gas in my pressure washer?
Yes. For the Craftsman 580767301 gas pressure washer, we use regular unleaded gasoline; 87 octane is the standard choice for this type of small engine. The bigger issue is keeping fuel fresh and preventing ethanol-related storage problems (especially if the washer sits).
What fuel to use (and what to avoid)
- Use fresh, regular unleaded gasoline (87 octane is fine).
- Avoid using old gas; stale fuel is a top cause of hard starting and surging.
- If your fuel is ethanol-blended, plan for storage protection because alcohol-blended fuels can attract moisture.
- Do not refuel on a hot engine; let the unit cool first.
- Always fuel outdoors and away from flames or sparks.
Best practices for ethanol fuel and storage
Alcohol-blended fuels (often labeled as ethanol blends) can cause fuel system issues during storage. If you will store the pressure washer for more than 30 days, we recommend treating the fuel and storing it correctly.
- Add a quality fuel additive/stabilizer following the additive instructions
- Fill with fresh gasoline (a partially filled tank can speed fuel deterioration)
- Run the engine briefly so treated fuel reaches the carburetor
- Shut off the fuel valve when done using the washer
For the model-specific storage steps and safety warnings, follow the owner's manual.
Quick reference table
| Situation | What we recommend | Why |
|---|---|---|
| Using the washer weekly | 87 octane, fresh gas | Reliable starting and steady power |
| Using the washer occasionally | 87 octane plus stabilizer | Reduces gum and varnish buildup |
| Storing over 30 days | Fresh gas plus additive; follow storage procedure | Helps prevent moisture separation and fuel system corrosion |
Why it matters
Fuel quality affects starting, throttle response, and engine life. Fresh 87 octane gasoline keeps the fuel-air mixture stable, and proper storage steps help prevent deposits in the carburetor, fuel hose, and filter.

What is the PSI of a gas-powered pressure washer?
For the Craftsman 580767301 gas pressure washer, the rated cleaning pressure is 2400 PSI. Gas-powered pressure washers as a category commonly range from about 2000 to 5000 PSI, but your exact PSI depends on the specific model and nozzle setup; confirm specs in the owner's manual.
PSI ranges: gas vs. electric (quick reference)
Typical pressure ranges you will see:
- Gas pressure washers: ~2000 to 5000 PSI
- Electric pressure washers: ~1200 to 3000 PSI (some heavy-duty electrics can be higher)
- Your Craftsman 580767301: 2400 PSI (rated)
| Type | Typical PSI range | Best for |
|---|---|---|
| Electric | 1200 to 3000 | Cars, patio furniture, light siding |
| Gas | 2000 to 5000 | Driveways, decks, heavy grime, faster cleaning |
What changes the “real-world” PSI you feel at the wand
Even with a 2400 PSI rating, performance at the spray tip can vary. Check these common factors:
- Nozzle condition: a clogged or restricted nozzle can cause pulsing and poor spray
- Water supply: use a steady supply and keep inlet water temperature at or below 100°F
- Inlet screen and filters: debris reduces flow and affects pressure
- Hose condition: kinks, cuts, or loose fittings reduce pressure
- Unloader valve and pump health: problems here can cause pressure spikes or weak output
Why it matters
Choosing the right PSI helps you clean efficiently without damaging surfaces. Higher PSI is not always better; using the correct spray tip and maintaining good water flow often improves results more than “more pressure.”
If pressure is pulsing or seems too low
We recommend these quick checks first:
- Turn off the engine and water; then clean the nozzle and in-line filter
- Verify all hose connections are tight and the high-pressure hose is not damaged
- Confirm you have at least 10 feet of unrestricted garden hose between the inlet and any shut-off device
- Make sure the water supply valve is fully open

How do I find the model number on my 580767301?
The model number is printed on the pressure washer’s model data label; for this Craftsman unit, it appears as 580.767301 in the documentation. Match the number on your label to the format shown in the 580767301 owner's manual so you order the correct parts.
Where to look on the pressure washer
Check these common label locations first (look for a sticker or metal tag):
- On the main frame/base near the pump mounting area
- On or near the handle/upright frame
- Near the engine mounting plate (not on the recoil cover)
- Close to the hose connection area or accessory storage
- On the underside of the base (tip the unit safely and look along the edges)
What the correct model number looks like
In the manual, the model is shown with a dot format:
| What you see | What it means |
|---|---|
| 580.767301 | The full Craftsman pressure washer model number |
| 580767301 | The same model number without the dot (often used online) |
Tips to avoid ordering the wrong parts
Using the exact model number matters because hose fittings, pump components, and hardware can vary by model.
- Write down the full model number exactly as printed
- If there is a type or revision code on the label, record that too
- Use the model number to match diagrams before ordering
- If you are replacing a hose or gun accessory, confirm the connection style first
- Keep your manual handy for parts list callouts and exploded views
Why it matters
The Craftsman 580767301 is a 2400 PSI, 2.2 GPM pressure washer; parts like the high-pressure hose, thermal relief components, and mounting hardware are selected by model to ensure proper fit and safe operation.
